Abstract

Medium Sterilization which has been packaged in the baglog on the oyster mushroom cultivation, one of them can be done with a steam technique using the drum. Commonly used fuel is firewood that could be assisted by using coal or kerosene or LPG gas. Rice husk as alternative fuel of kerosene and firewood can be used as fuel for the medium sterilization. The husk which used in the sterilization process of oyster mushrooms medium for 6 hours, 8 hours, and 10 hours as much as 55.5 kg, 60 kg and 67 kg. The efficiency which obtained in the medium sterilization of oyster mushrooms with using rice husk is reached 45.23% in the medium sterilization for 8 hours.   Keywords: Medium, oyster mushrooms, rice husk, sterilization

Abstract

Sterilization media were done in drum. Fuels LPG.is used for the fuel Efficiencies of the fuel gained in the media sterilization oyster mushrooms for 6 hours is 40.74%, meanwhile efficiencies of the fuel for 8 and 10 hours is 59.57% and 53.14%. The physical and economical research of the white oyster mushrooms sterilization process for 8 hours produces the highest efficiency.   Keywords: Medium, oyster mushrooms, LPG, sterilization

Abstract

Rice husk furnace  is a technology based on local wisdom to anticipate threats crisis energy. At first investigated husk stoves for cooking only in the scale of the household, but today rice husk furnace developed for industrial scale because of the importance of commercial aspects of a very promising from this rice husk furnace. In rice husk furnace also developed an industrial scale boiler system, boiler systems where it can enlarge its efficiency, in the midst of a boiler chimney pots have used, because basically rice husk furnace process is influenced by air flow. Husk furnace efficiency greatly affect the number of furnace ash which is required in the cooking process.   Keywords: rice husk, rice husk furnaces, air flow, efficiency, boilers.
